  • Steam, launching Team Fortress 2: libGL.so.1: wrong ELF class: ELFCLASS64

    - by stefanhgm
    After I got Steam running with the workaround mentioned here, I've got nearly the same problem when launching Team Fortress 2. After starting it from Steam the "Launcher" pops up and after a few seconds it disappears with the following error in the terminal: /home/user/Steam/SteamApps/steamuser/Team Fortress 2/hl2_linux: error while loading shared libraries: libGL.so.1: wrong ELF class: ELFCLASS64 Game removed: AppID 440 "Team Fortress 2", ProcID 5299 saving roaming config store to 'sharedconfig.vdf' roaming config store 2 saved successfully Because of the similarity with the workaround I used before, I tried to execute: export LD_LIBRARY_PATH=/usr/lib32:$LD_LIBRARY_PATH directly before launching the game, but there is no difference.

  • problems programmatically creating UIView on iPad App

    - by user3871
    I have been struggling with this problem for a few days. My iPad app is designed to be a portrait game. To satisfy Apple's expection, I also support landscape mode. When it goes into landscape mode, the game goes into a letterbox format with back borders on the sides. My problem is I am creating the UIWindow and UIView programmatically. For some unkown reason, the touch controls are "locked" in to think I'm always in landscape mode. And even though visually in portrait mode everything looks correct, the top and bottom of the screen does not respond to touch. To summarize how I am setting this up, let me provide the skeletal framework of what I'm doing: in main.cpp: int retVal = UIApplicationMain(argc, argv, nil, @"derbyPoker_ipadAppDelegate"); In the delegate, I am doing this: - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { CGRect screenBounds = [[UIScreen mainScreen] bounds]; CGFloat scale = [[ UIScreen mainScreen] scale ]; m_device_width = screenBounds.size.width; m_device_height = screenBounds.size.height; m_device_scale = scale; // Everything is built assuming 640x960 window = [[ UIWindow alloc ] initWithFrame:[[UIScreen mainScreen] bounds]]; viewController = [ glView new ]; [self doStateChange:[blitz class]]; return YES; } The last bit of code sets up the UIView... - (void) doStateChange: (Class) state{ viewController.view = [[state alloc] initWithFrame:CGRectMake(0, 0, m_device_width, m_device_height) andManager:self]; viewController.view.contentMode = UIViewContentModeScaleAspectFit; viewController.view.autoresizesSubviews = YES; [window addSubview:viewController.view]; [window makeKeyAndVisible]; } The problem seems to related to the line viewController.view.contentMode = UIViewContentModeScaleAspectFit; If I remove that line, touch works correctly in portrait mode. But the negative is when I'm landscape mode, the game stretches incorrectly. So That's not a option. The frustrating thing is, when I originally had this set up with a NIB file, it worked fine. I have read through the docs about UIWindow, UIViewController and UIView and have tried about everything to no avail. Any help would be greatly appreciated.

  • Microsoft joins the rest of us...and counts down to the end of IE6

    - by brian_ritchie
    Microsoft launched a website dedicated to the demise of IE6.  Here's their pitch...10 years ago a browser was born.  Its name was Internet Explorer 6. Now that we’re in 2011, in an era of modern web standards, it’s time to say goodbye. We'll watch Internet Explorer 6 usage drop to less than 1% worldwide, so more websites can choose to drop support for Internet Explorer 6, saving hours of work for web developers.  Thanks Microsoft!  We've been waiting for this day to come for a long time.  Of course, it would have been nice if IE6 was gone 5 years ago...but who's counting.

  • What stack of technologies should I use for my online game?

    - by Vee Bee
    I built a TicTacToe game to learn the .Net MVC3 framework. The basic functionality works (display board, make a move, detect winning move etc.) What I'd like to do is make it a "real" application - well-architected and using the right technology at the right layer. For instance, I'm currently saving every move to the database via a service call, which feels klugey and may become a bottleneck if this was an MMO game. How do you determine a good architecture (or right set of technologies) to use in a situation like this? I'd like to learn not just what to do, but why certain decisions are better than others. I noticed a similar thread here but it just offered opinions without explaining WHY something would be better (e.g. why Node instead of MVC3, etc.)

  • Is it safe to configure "Shutdown" on "When laptop lid is closed" ?

    - by Takkat
    To setup a laptop owned by a complete PC novice any settings that may become hard to tackle remotely need to be avoided. The laptop will be administrated via SSH. One thing in my list are problems arising from improper wake-ups from suspend or hibernate as they may also affect network accessibility. This is why I thought setting up power management to "shutdown" on closing the laptop lid could be a good idea. However I am not sure if this is a safe way to do. What problems in addition to software not closing properly (and thus not saving their data) could I be faced if I proceeded as planned?

  • Bullet Physics implementing custom MotionState class

    - by Arosboro
    I'm trying to make my engine's camera a kinematic rigid body that can collide into other rigid bodies. I've overridden the btMotionState class and implemented setKinematicPos which updates the motion state's tranform. I use the overridden class when creating my kinematic body, but the collision detection fails. I'm doing this for fun trying to add collision detection and physics to Sean O' Neil's Procedural Universe I referred to the bullet wiki on MotionStates for my CPhysicsMotionState class. If it helps I can add the code for the Planetary rigid bodies, but I didn't want to clutter the post. Here is my motion state class: class CPhysicsMotionState: public btMotionState { protected: // This is the transform with position and rotation of the camera CSRTTransform* m_srtTransform; btTransform m_btPos1; public: CPhysicsMotionState(const btTransform &initialpos, CSRTTransform* srtTransform) { m_srtTransform = srtTransform; m_btPos1 = initialpos; } virtual ~CPhysicsMotionState() { // TODO Auto-generated destructor stub } virtual void getWorldTransform(btTransform &worldTrans) const { worldTrans = m_btPos1; } void setKinematicPos(btQuaternion &rot, btVector3 &pos) { m_btPos1.setRotation(rot); m_btPos1.setOrigin(pos); } virtual void setWorldTransform(const btTransform &worldTrans) { btQuaternion rot = worldTrans.getRotation(); btVector3 pos = worldTrans.getOrigin(); m_srtTransform->m_qRotate = CQuaternion(rot.x(), rot.y(), rot.z(), rot.w()); m_srtTransform->SetPosition(CVector(pos.x(), pos.y(), pos.z())); m_btPos1 = worldTrans; } }; I add a rigid body for the camera: // Create rigid body for camera btCollisionShape* cameraShape = new btSphereShape(btScalar(5.0f)); btTransform startTransform; startTransform.setIdentity(); // forgot to add this line CVector vCamera = m_srtCamera.GetPosition(); startTransform.setOrigin(btVector3(vCamera.x, vCamera.y, vCamera.z)); m_msCamera = new CPhysicsMotionState(startTransform, &m_srtCamera); btScalar tMass(80.7f); bool isDynamic = (tMass != 0.f); btVector3 localInertia(0,0,0); if (isDynamic) cameraShape->calculateLocalInertia(tMass,localInertia); btRigidBody::btRigidBodyConstructionInfo rbInfo(tMass, m_msCamera, cameraShape, localInertia); m_rigidBody = new btRigidBody(rbInfo); m_rigidBody->setCollisionFlags(m_rigidBody->getCollisionFlags() | btCollisionObject::CF_KINEMATIC_OBJECT); m_rigidBody->setActivationState(DISABLE_DEACTIVATION); This is the code in Update() that runs each frame: CSRTTransform srtCamera = CCameraTask::GetPtr()->GetCamera(); Quaternion qRotate = srtCamera.m_qRotate; btQuaternion rot = btQuaternion(qRotate.x, qRotate.y, qRotate.z, qRotate.w); CVector vCamera = CCameraTask::GetPtr()->GetPosition(); btVector3 pos = btVector3(vCamera.x, vCamera.y, vCamera.z); CPhysicsMotionState* cameraMotionState = CCameraTask::GetPtr()->GetMotionState(); cameraMotionState->setKinematicPos(rot, pos);

  • Top ten most active programming sites to run an ad campaign [closed]

    - by fabbianni
    Hello friends, I'm looking for a new investment in the programming area, I'd like to know about the state of the art in the programming sites you usually visite, like stackoverflow. Not sure if sites like thecodeproject (and similar) are too old fashioned these days. I'm a programmer, but honestly haven't been too involved in the programming arena mostly for admin issues. I'm looking for sites with both great audience and great content, and open to ads, again, like stackoverflow. thanks !

  • How can I copy data from a windows disk to another partition?

    - by TardisGuy
    I have a new Solid State Drive, and it's very fast (but tiny, 128GB). But it seems to be much faster in Linux. Now, am I correct in assuming that if I Gparted copy paste the {_Boot MSreserved__][_________NTFS__________] in to (1st Empty space, same partition) and it will be bootable, right? Will this work? I also heard I should turn off 'journaling' for the SSD filesystem. Is that needed for this as well?

  • thunderbird-bin causing CPU (core) lockup (12.04, 64bit, up-to-date)

    - by david6
    I have experienced 2-3 unexplained lockup over last 10 days. Today, I had a random lockup (no mouse, keyboard response, 100% CPU). But, when I finally switched (Ctrl-Alt-F1) to command line (it took several minutes) it told me that thunderbird-bin had locked a CPU. I ran this to resolve: pidof thunderbird-bin sudo kill #### However, after saving other work, I tried restarting Thunderbird. It went to 90%+ CPU, and within 20 seconds it locked again. Once I have more detail I will raise a bug (on Ubuntu Forums). Does anyone have any other suggestions, advice?

  • Tool Review: Telerik JustDecompile

    - by Sam Abraham
    In the next few lines, I will be providing a brief review of Telerik’s JustDecompile, a free .Net decompiler and assembly browser. In using Telerik’s 2012 Q3 JustDecompile release, one can see many great features.  First off, I loved the built-in options for loading .Net assemblies automatically using the Open->Load Framework menu option. Other options enable loading assemblies from GAC, XAP URL or locally from disk. The ability to create an “Assembly List” is quiet handy for grouping and saving a “List” of DLLs to load. All loaded assemblies are shown in the left panel of a split-panel screen. Clicking an assembly expands all namespaces within. Drilling further to class level displays the actual source code in the right panel in either IL, C# or Visual Basic. In conclusion, JustDecompile has grown and quickly matured into an indispensible handy tool for us developers. Telerik’s effort in maintaining and updating JustDecompile as well as the company’s commitment to keeping it free is much appreciated and valued.

  • How to run software, that is not offered though package managers, that requires ia32-libs

    - by Onno
    I'm trying to install the Arma 2 OA dedicated server on a Virtualbox VM so I can test my own missions in a sandbox environment in a way that lets me offload them to another computer in my network. (The other computer is running the VM, but it's a windows machine, and I didn't want to hassle with its installation) It needs at least 2, and preferably 4GB of ram, so I thought I would install the AMD64 version of ubuntu 13.10 to get this going. 'How do you run a 32-bit program on a 64-bit version of Ubuntu?' already explained how to install 32bit software though apt-get and/or dpkg, but that doesn't apply in this case. The server is offered as a compressed download on the site of BI Studio, the developer of the Arma games. Its installation instructions are obviously slightly out of date with the current state of the art. (probably because the state of the art has been updated quite recently :) ) It states that I have to install ia32-libs, which has now apparently been deprecated. Now I have to find out how to get the right packages installed to make sure that it will run. My experience level is like novice-intermediate when it comes to these issues. I've installed a lot of packages though apt-get; I've solved dependency issues in the past; I haven't installed much software without using package managers. I can handle myself with basic administrative work like editing conf files and such. I have just gone ahead and tried to install it without installing ia32-libs through apt-get but to install gcc to get the libs after all. My reasoning being that gcc will include the files for backward compatibility coding and on linux all libs are (as far as I can tell) installed at a system level in /libs . So far it seems to start up. (I can connect with the game server trough my in-game network browser, so it's communicating) I'm not sure if there's any dependency checking going on when running the game server program, so I'm left with a couple of questions: Does 13.10 catch any calls to ia32libs libraries and translate the calls to the right code on amd64? If it runs, does that mean that all required libraries have been loaded correctly, or is there a change of it crashing later on when a library that was needed is missing after all? Is it necessary to do a workaround such as installing gcc? How do I find out what libraries I might need to run this software? (or any other piece of 32-bit software that isn't offered through a package manager)

  • How do I disable Caps Lock by command line?

    - by Echogene
    For some reason my laptop is stuck in Caps Lock. I have the Caps Lock key mapped by xmodmap to hyper_l, so I don't have a caps_lock key to turn it off. Is there a way I can turn it off by command line? It would be nice if I could reset the lock state without resetting my computer, especially for future reference. This has happened before, but I would like to know now how to do it properly this time.

  • aticonfig detects all graphics cards, but amdcccle shows the cards as disabled

    - by DevZer0
    I been having the strangest problem since few days ago. I have 3 ATI graphics cards and the aticonfig --list-adapter shows the following output * 0. 01:00.0 AMD Radeon HD 7900 Series 1. 02:00.0 AMD Radeon HD 7900 Series 2. 05:00.0 AMD Radeon HD 7900 Series when i do aticonfig --adapter=all --initial -f it generates the correct X config also. but after rebooting the output only show on primary monitor and when i look in amdcccle it shows the other 2 adapters as disabled. I tried with monitors attached and dummy plugs both but the situation doesn't change. Any idea whats causing this? also right clicking and making the adapter enabled in amdcccle and saving changes causes the X config to only have the adapter section and no screen section. after reboot the situation stays the same.

  • Are closures with side-effects considered "functional style"?

    - by Giorgio
    Many modern programming languages support some concept of closure, i.e. of a piece of code (a block or a function) that Can be treated as a value, and therefore stored in a variable, passed around to different parts of the code, be defined in one part of a program and invoked in a totally different part of the same program. Can capture variables from the context in which it is defined, and access them when it is later invoked (possibly in a totally different context). Here is an example of a closure written in Scala: def filterList(xs: List[Int], lowerBound: Int): List[Int] = xs.filter(x => x >= lowerBound) The function literal x => x >= lowerBound contains the free variable lowerBound, which is closed (bound) by the argument of the function filterList that has the same name. The closure is passed to the library method filter, which can invoke it repeatedly as a normal function. I have been reading a lot of questions and answers on this site and, as far as I understand, the term closure is often automatically associated with functional programming and functional programming style. The definition of function programming on wikipedia reads: In computer science, functional programming is a programming paradigm that treats computation as the evaluation of mathematical functions and avoids state and mutable data. It emphasizes the application of functions, in contrast to the imperative programming style, which emphasizes changes in state. and further on [...] in functional code, the output value of a function depends only on the arguments that are input to the function [...]. Eliminating side effects can make it much easier to understand and predict the behavior of a program, which is one of the key motivations for the development of functional programming. On the other hand, many closure constructs provided by programming languages allow a closure to capture non-local variables and change them when the closure is invoked, thus producing a side effect on the environment in which they were defined. In this case, closures implement the first idea of functional programming (functions are first-class entities that can be moved around like other values) but neglect the second idea (avoiding side-effects). Is this use of closures with side effects considered functional style or are closures considered a more general construct that can be used both for a functional and a non-functional programming style? Is there any literature on this topic? IMPORTANT NOTE I am not questioning the usefulness of side-effects or of having closures with side effects. Also, I am not interested in a discussion about the advantages / disadvantages of closures with or without side effects. I am only interested to know if using such closures is still considered functional style by the proponent of functional programming or if, on the contrary, their use is discouraged when using a functional style.

  • Looking for a non-cryptographic hash function that returns a single character

    - by makerofthings7
    Suppose I have a dictionary of ASCII words stored in uppercase. I also want to save those words into separate files so that the total word count of each file is approximately the same. By simply looking at the word I need to know which file it should be in (if it's there at all). Duplicate words should go into the same file and overwrite the last one. My first attempt at solving this problem is to use .NET's object.GetHashCode() function and .Trim() to get one of the "random" characters that pop up. I asked a similar question here If I only use one character of object.GetHashCode() I would get a hash code character of A..Z or 0..9. However saving the result of GetHashCode to disk is a no-no so I need a substitute. Question: What algorithm (or subset of an algorithm) is appropriate for pigeonholing strings into a single character or range of characters (Like hex 0..F offers 16 chars)? Real world usage: I'll use this answer to modify the Partition key used in Azure Table storage as described here

  • How to edit files in a terminal with vim?

    - by andrew.46
    It is not always possible to edit and create files in a terminal and I would like to get the answers to the basics of manipulating files in a terminal using vim under Ubuntu Linux. Specific questions I have are: How can I open text files for editing? How can I save the file? How can I save the file with a different name? How can I leave the file without saving the changes? What settings are best in my configuration file and where is this file? How do I set the colors for vim? How do I show line numbers in vim and can this be toggled? A lot of questions here but I believe these questions and their answers should cover basic vim usage...
